Professional Outbuildings & Garden Rooms for Ottery St Mary Properties
The demand for high-quality outbuildings and garden rooms has grown enormously, and Brick Builds constructs them to the same standard as any other building project — with proper foundations, structural walls, insulation, electrical supply and high-specification finishes. Whether you need a home office in the garden, a gym or studio, a detached garage or a fully insulated annexe for a family member in Ottery St Mary, we design and build it to last.
Our outbuildings in Devon are built in brick, stone or timber frame depending on your preference and planning requirements. Unlike many garden room suppliers who install flat-pack structures with minimal foundations, everything we build in Ottery St Mary is constructed properly from the ground up — with correct drainage, weatherproofing, insulation to Part L standards and electrical installation by certified contractors. The result is a building that adds real, lasting value to your Devon property.
An outbuilding or garden room can be constructed under Permitted Development in most Devon properties, provided it meets the relevant size, height and use restrictions. We advise on this as part of our initial consultation and handle the full build process in Ottery St Mary from groundworks through to decoration — including plumbing and electrics coordination. We also carry out larger detached annexe builds that require full planning permission across Devon.
